I think perhaps in that context, something like "this is terrible/awful" would be more fitting? And in my experience, it's not mainly working-class people who use "sucks". I have a mixture of friends, working class and "upper" class, and it's actually the upper class people who tend to use it more. The same people who use "awesome", so i think it's generally, like Lord Great Chamberlain said, people who have decided to use a few Americanisms. I'm not working class, but i've used "sucks" a few times in my life when it fits better than anything else.Originally Posted by Schmerg_The_Impaler
And as for Chick. Guys very very rarely use it anymore. But girls might use it to describe each other, i think mostly in a context like the one you've written, Schmergo, when insulting another girl. "Look at that what she's wearing. I swear, that chick needs some dress-sense" or something.
But i honestly think "sucks" has nothing to do with what class a person is in, but the environment they live in.
